PMVCM bit
MCKPD bit
PMPLL bit

<Example>
BICK pin
MCKI pin
FCK pin
PDN pin
(1) After Power Up: PDN pin “L” → “H”
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0” → “1”
(4) Release the pull-down resistor of the MCKI pin: MCKPD bit = “1” → “0”
(5) Normal operation starts after the MCKI, FCK and BICK are supplied.
“L” time (1) of 150ns or more is needed to reset the AK4632.
VCOM should first be powered up before the other block operates.
Power down PLL: PMPLL bit = “0”
